They were driving to dinner. He had been going on about something. He really couldn't remember. What he could remember was her leaning over and speaking directly into his ear. "Stop it or you WILL be slapped."
His cock had been hard ever since. Was it the threat that had gotten to him? Her voice? The promise? He wasn't really sure. All he really knew was that every time he even glanced at her his cock jumped in his pants. He was sure if he looked down there would be a stain of pre-cum on his pants. He thought she had no idea what she had done to him.
She was sitting there at dinner talking about the day and their plans for the weekend. He really couldn't wait to get home and fuck her 'til she couldn't see straight.
When they finally did get home he couldn't help but push her up against the wall and start kissing her. He had his hands on both sides of her head and was running his tongue all around her mouth. He put a hand behind her back to pull her close and let her feel his hardness pressing against her. He couldn't wait. He had to feel her lips closed around his cock. He pushed her down to her knees for her to free his cock.
She was smiling up at him so sweetly. So hungrily. Now that his cock was free she was softly caressing it. Teasing him with her nails. Watching the reactions flash across his face. He tipped his head back reveling in the pleasure.
"Feel good?" She cooed.
"Oh, yes." He sighed.
That's when she grabbed his cock firmly by the base and slapped it. Hard. He head snapped forward as his eyes flew open. "Hey!" He yelped looking at her a little surprised.
